LISTEN UP, GUYS!I HAVE THE SAME PROBLEM WATCHING BDRIP FILMS ON MY PS3. THAT ANNOYING WINDOW POPS OUT SAYING THAT THE AUDIO OUTPUTS HAVE BEEN TEMPORALY MUTED AND BLAH BLAH BLAH.I CAME UP WITH THE SOLUTION WE SO DESPERATELY WERE LOOKING FOR. CHECK OUT THIS LINK;http://rocom.tumblr.com/post/2495162905, ALL YOU GOTTA DO IS THERE!IT'S EASY AS CRAP AND REALLY WORKS!! BELIEVE ME!!

HOWEVER, IN CASE THAT LINK DOESNT WORK I'LL EXPLAIN IT MYSELF. 1. Go to your sound settings 2. Select audio output settings 3. Switch from HDMI to optical digital (even if you use HDMI) 4. Select every setting there is, then SAVE IT. 5. Once its saved, it will take you back to sound settings, select audio multi-output and turn it ON.GOOD LUCK!!!

This will simply remux the MKV with a re-encoded audio stream (from DTS to AC3) into a PS3 native MPG w/AC3 (no transcode required to stream with PMS ). The DTS-->AC3 re-encode takes about 5-10 minutes MAX with a full length movie, then MKV2VOB will remux the new AC3 audio with the untouched video stream (another 5 or so minutes). This will leave you with an AC3 track instead of DTS, but it will still be at 640kbps or 448kbps if you so choose, and will now work. Better than the file not working because it's infected.

Of course for you MKV2VOB users out there, you would need to change back any settings to use it for it's usual purpose.

EDIT: I can confirm that this does in fact work for my copy of The Losers w/DTS audio

With M2TS files that have DTS, I would simply add another step between step 1 and 2. Use MKVMERGE (version 3.4.0 or older)to remux the M2TS to an MKV (this allows compatibility to MKV2VOB) Then add that file to MKV2VOB and continue on with steps I provided.

These steps may be "too much" for some people. If you fall into this category, I suggest then, as I always have, to find sources that DO NOT have CINAVIA DRM if this is too much, but doing so will require time to search for and download a new Cinavia DRM free file (these "infection" free files are available online from many release groups). My steps take around or less than half an hour to get playable, Cinavia DRM free files, and save users from having to find their own DTS fix.

MP4's should never have DTS for an audio stream, as well I have never seen AVI with DTS as of yet so my suggestions, combined with the link Yakos provided SHOULD eliminate MOST Cinavia DRM issues out there.

Of course FOOBAR 2000 has a DTS decoder that works quite well, but I have not devised an easy to follow system for this route just yet.
